したことを特徴とするものである。In order to solve the above-mentioned problems, the present invention relates to a heating furnace, wherein an exhaust gas nozzle portion is provided at a position outside a heating object carrying-in / out opening, and the heating furnace is provided with an exhaust gas nozzle. The exhaust gas inside the chamber absorbs heat and is guided to the exhaust gas nozzle through an exhaust blower.At the location outside the opening, the exhaust gas is ejected in the same direction as the vertical movement of a door provided at the opening. The exhaust gas curtain is formed outside the opening.

く、人体への加熱影響はきわめて少ない。The combustion gas in the furnace is guided by a blower to an exhaust gas ejecting portion provided at the heated object carry-in / out opening, and outside the opening, a vertical movement direction of a door provided at the opening is determined. It blows out in the same direction to form an exhaust gas curtain. Although such an exhaust gas curtain partially enters the furnace, this is rather effective for reducing the generation of nitrogen oxides, and since the exhaust gas is a gas after endothermic, the temperature is low, The heating effect on the human body is extremely small.

図ることができる。DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a heating furnace, and 2 denotes a burner provided in the heating furnace. In the embodiment of the present invention, the heating furnace 1 includes:
Two burners are installed, and the two burners 2 are alternately burned. When one burns, the exhaust gas is discharged from the other and guided to the exhaust gas nozzle unit 4 through the blower 3. Make up. During this time, the exhaust gas is appropriately heat-exchanged.
The temperature is reduced by absorbing heat by means.
Reference numeral 5 denotes a heated object carry-in / out opening.
, A door 6 that moves up and down is installed. The exhaust gas spout 4
Is installed at a lower portion outside the heated object opening 5. Therefore, during the operation, when the door 6 is in the half-door state, the loading and unloading of the object to be heated is performed from the opening of the opening 5.
For example, it repeats every 30 seconds. At this time, the blower 3
As a result, the combustion exhaust gas is guided from the inside of the furnace to the exhaust gas ejection section 4, and the exhaust gas is ejected in the same direction as the vertical movement of the door 6, as shown in the figure. The discharged exhaust gas forms an exhaust gas curtain 7 as shown in the figure, shuts off the inside of the furnace and the outside air, and the object to be heated is repeatedly carried in and out through the exhaust gas curtain 7. Part of the exhaust gas enters the furnace, which rather promotes the combustion of the exhaust gas and contributes to suppressing the generation of nitrogen oxides. In this case, the atmosphere gas in the furnace and the exhaust gas curtain have almost the same components, so that there is no problem in affecting the object to be heated. Since the exhaust gas curtain is exhaust gas after heat absorption, the temperature is low, and there is no heating of the furnace outside, and as a result, there is no influence on the human body due to radiant heat or the like. In addition, unlike the frame curtain, no fuel gas is used, so that significant cost reduction can be achieved.
